Polishing can be divided into manual polishing and electrolytic polishing. The biggest problem with manual polishing is that it relies on a lot of labor. The labor intensity is high, and the power and material consumption are also large. Electrolytic polishing is easy to operate, high in effect, low in cost, and can be thrown to dead angles that cannot be polished by manual polishing. Therefore, the electrolytic polishing process should be used as much as possible in production. Electrolytic polishing is the reverse behavior of electroplating. It can remove the remainder of 1-5 wires on the surface of the workpiece. Electrolytic polishing is carried out under the action of electrolyte and current. The important principle is micro peaks are preferentially removed without altering the macroscopic profile of the workpiece. The surface finish is obtained directly from the electrolytic bath to reduce or even avoid the heavy workload of manual polishing.

There are many surface treatment processes for stainless steel fastener products. For example cleaning and degreasing, rust removal, passivation, pickling, rust prevention, polishing, electroplating, electrophoresis, etc. Each stainless steel fabricator will choose different surface treatment methods according to their own production process needs.

In recent years. the more mature and extensive processes used include surface treatment processes such as stainless steel pickling passivation and stainless steel electrolytic polishing. After the workpiece is electrolytically polished, a passivation layer will be formed on the surface to improve corrosion resistance.

The surface of the stainless steel workpiece after electropolishing treatment shows absolutely consistent brightness and delicate effect, and its surface gloss can reach an 8K mirror effect. And lasting bright as new, never peeling off. It is the best choice as an alternative to traditional mechanical and manual polishing.
